WordPress automatically pings itself and adds a comment to a post whenever you link to another article on your site. Some site owners like it, others hate it. If you fall in the second camp, No Self Pings is a WordPress plug-in that you should check out as it keeps your comment section free of self-ping updates. No Self Pings hasn't been updated in two years, but it's compatible with the latest version of WordPress (3.5.1 at the time this story was written).
